Will this motor drop into a SINAMICS S120 line with the rest of the SIMOTICS 1FK2 fleet?
The 1FK2104-4AK00-2SB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family paired with SINAMICS S120 drives, supplied as 1 Piece per carton and identified under Group Code R220 / Product Group 9021. It is built to order under product class C, meaning each unit is configured and produced against the order rather than held as a returnable stock item. Standstill torque M0 is 1.27 Nm, with a rated output PN = 0.6 kW at nN = 6000 rpm on a 380-480 V supply, and a second operating point of PN = 0.4 kW at nN = 3000 rpm on a 200-240 V supply — the same frame is sold into both 230 V class and 400 V class S120 line-ups, and the drive parameter set has to match the band the cabinet actually delivers.
Encoder, shaft, and the mechanical side of the BOM line
Feedback is an absolute single-turn 22-bit encoder (AS22DQC), giving 4 194 304 positions per revolution with no battery backup required — multi-turn is not on this code, so any application that needs true position retention across power-down needs an absolute multi-turn variant or a gearbox reference scheme elsewhere in the line. The shaft is a plain cylindrical D14 x 30 mm, balanced without a keyway on this code, which simplifies alignment but means the coupling is the only thing resisting torque transmission under shock load — the DRIVE-CLiQ M17 feedback plug and the M17 power connector both rotate relative to the housing, so the cabinet layout has to leave swing room for the cable bend radius.
IP64 in plain terms — what the sealing actually covers
Degree of protection is IP64: dust-tight and resistant to splashing water from any direction, which is the rating the SIMOTICS 1FK2 HD series typically carries when ordered for cabinet-internal or light industrial duty. It is not IP65/IP67 washdown-rated — a food-and-bev line with hose-down cleaning needs a higher-rated variant, not this code.
Drive side: DRIVE-CLiQ and the SINAMICS topology
The DRIVE-CLiQ M17 interface carries both the encoder data and motor identity to the SINAMICS S120 drive, so electronic nameplate recognition is automatic once the cable is seated — the drive auto-loads motor parameters and the matching motor-side power connector is also M17, keeping the cable family consistent on this frame size.
Compliance and documentation the buyer will be asked for
The motor has been RoHS-compliant since 01-07-06 and the supplier publishes Reach information under Article 33 for candidate-list substances — both are the buyer-side documentation asks for any EU ship-to.
